Dreamball:Orb Hunt

Introduction

Creating an Orb Hunt map is done from mapping tricks using existing Source entities, no custom Dreamball entities are used here. This tutorial will cover creating a simple 1 orb map. To create the extra orbs you just simply repeat the building process.

Construction

First let's create the orb effect. Place a env sprite where your orb's position will be. Name it orb_sprite1 and set it's Sprite Name material to sprites/orb01.vmt, it's scale to 1.5, it's Size of Glow Proximity to 2.0 and lastly the Render Mode field to Additive. Also check it's flag to Start On.

Now place an info particle system. Name it orb_destroy1 and set it's particle effect name to orb01 and it's Start Active field to No. Place another info_particle_system and name it orb_destroy1_warp. Set it's particle effect name to warp_explosion1. And Start Disabled flag to to Yes.

Now place an env screenoverlay entity. Name it 1orb. Set overlay name to overlays/orbs/1orb and make sure the Overlay Duration fields are set to 0 seconds. We use image overlays to display the '1/12 Orbs Collected' in the official maps but you can use a game text if desired.

Now place an ambient generic entitiy. Set it's sound to ambient/levels/labs/electric_explosion4.wav. Name this entity orb_explode_snd

Create a small trigger once brush over the orb sprite. Shaped around it, so it looks like you hit the orb when hitting the trigger. Name this trigger orb_trig1. Now in it's outputs tab add these:

	My Output >	Target Entity	Target Input	Parameter	Delay	Only Once
	OnStartTouch	orb_destroy1	Start	None	0.00	Yes
	OnStartTouch	orb_explode_snd	PlaySound	None	0.00	Yes
	OnStartTouch	orb_destroy1_warp	Start	None	0.00	Yes
	OnStartTouch	orb_sprite1	Kill	None	0.00	Yes

Now that's the Orb itself set up. Now Place a math counter entity and name it orb_math. With it's following fields set to:

• Start Disabled: No
• Initial Value: 0
• Minimum Legal Value: 0
• Maximum Legal Value: 1 (or more if you are using more orbs)

We'll add the outputs for the orb_math in after the next bit.

place a logic case entity and name it Orb_score_case. In it's field named Case 01, add 1. (add the rest for Case_02 - 2, Case_03 - 3 and so on for more orbs.) Now in this entity add these outputs:

	My Output >	Target Entity	Target Input	Parameter	Delay	Only Once
	OnCase01	1orb	StartOverlays	None	0.00	No
	OnCase02	1orb	StopOverlays	None	0.00	No

Although this tutorial is for 1 orb, we'll still add the OnCase02 StopOverlays, assuming your doing more. Note you always need to stop the older overlay when calling a new one because they will just display over each other otherwise.

Now back to that orb_trig1 brush, add these output:

	My Output >	Target Entity	Target Input	Parameter	Delay	Only Once
	OnStartTouch	orb_math	Add	1	0.00	No

Now open the orb_math entity and add these output:

	My Output >	Target Entity	Target Input	Parameter	Delay	Only Once
	OutValue	Orb_score_case	InValue	None	0.00	No

Conclusion

That is the base of the game mode done, you should have 1 orb ready for hunting! Repeat the process to get more orbs.

Tip:See the sdk_sp_orb1.vmf example in the "Dreamball Dev Kit/SDK_content/mapsrc/" folder for an example map.
